This Account outlines our efforts in the design and synthesis of a family of highly effective atropisomeric dipyridylphosphine ligands (P-Phos and its variants) and in the development of their widespread applications in transition-metal-catalyzed asymmetric reactions including hydrogenation, hydrosilylation, and C-C...
Articles
The P-Phos ligand family was developed by Professor Chan of Hong Kong Polytechnic University and licensed to JM CCT in 2002. P-Phos is an atropisomeric biaryl bisphosphine with the unique feature of incorporating two methoxy-substituted pyridine rings in the backbone.
